Dyntopo: Solve issue with test file by Jens.

Browse Source 
Seems like custom data indices can be mangled when many layers are
present in the mesh, so use more strict calculation of offset (copied
over from BM_CD_LAYER_ID).

I was under the impression that all custom data would be deleted on
entering dyntopo, it seems this is not the case though.
